摘　　要：由于异种导线的风摆幅值、周期差异较大,导致导线不同步摆动引起档中水平相间距离不足的问题,对架空输电线路采用异种导线的相间距离进行数学建模、定量计算。结果表明,若采用异种导线,须对档距进行控制,对于小档距,可通过增加塔头回路水平间距来解决相间距离不足的问题,但对于大档距,因异种导线不同步摆动无法满足相间距离要求,不可采用异种导线。Due to the large difference in the wind swing amplitude and cycle of different types of conductors,the problem of insufficient horizontal inter phase distance in the span caused by unsynchronized swing of conductors will occur.In this paper,the mathematical model and quantitative calculation are made for the inter phase distance of different conductors in overhead transmission lines.The results show that if different conductors are used,the span must be controlled.For small span,the problem of insufficient inter phase distance can be solved by increasing the horizontal distance of tower head circuit.However,for large span,the requirements of inter phase distance cannot be met due to the unsynchronized swing of different conductors.
